FIRE-PROOF MATERIAL.

SPECIFICATION forming' part of Letters Patent No. 290,837, dated December 25, 1883.

Application filed September 28, 1883.

T a/ZZ whom, it may concern,

Be it known that I, J OHN S. BEER, of the city of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Fire Proof Material, of which the following is a specification.

The object of this invention is to produce a strong and durable fire-proof fabric which is adapted to'be used in the manufacture of varions fire-proof articles for personal wear and other purposes-for instance, boots and shoes, gloves, aprons, and the like. I

Heretofore asbestus has been employed in various ways in the manufacture of fire-proof fabrics; but these fabrics are not sufficiently strong and durable for thepurpose for which my improved fabric is designed, and the articlesmanufactured from such fabrics soon lose their shape and become unfit for use.

My invention is designed to overcome this difficulty; and it consists ofthe improvement in the fire-proof fabric, which will be hereinafter fully set forth, and pointed out in the claims.

The accompanying drawing represents a sheet of my improved fabric.

A represents a sheet of iire proof fabric woven of asbestus, and provided, if desired, with strengthening-threads of wire `or other suitable material in a well-known manner.

B represents a backing, of canvas or other strong cloth,securedtothe fire-proof fabric A by numerous rows of stitching, c,vwhich are preferably arranged to intersect in the manner of quilting. The sheets A and B may be sewed together with fine wire, but for all ordinary purposesY common thread will answer, because the thread becomes embedded in the asbestus and the projecting bers of the asbestus will cover the thread and protect the same. In order to better protect the thread, the fabric,

(No model.)

after the two sheets have been sewed together,

is passed between a pair of pressing or caleni dering-rollers, whereby the projecting fibers of asbestus are closed down over the seams. The compound sheet of fabric so produced is very strong and durable and well adapted to be manufactured into gloves, aprons, boots, and shoes for blacksmiths, molders, firemen, and other persons exposed to fire, and into iiat-iron holders and other articles required to resist re and heat. In manufacturing these articles, the sheet, A, of asbestus is arranged on the outside or the side exposed tothe fire, and the sheet A protects the backing B from the fire, while the backing imparts vthe required strength and durability to the fabric.

When the fabric is designed for the manufacture of iireproof book-cases or portfolios, the backing B may be made of thin sheet inetal-copper 0r tin, for instance-and the fire-proof fabric A may be sewed to the metallic backing with wire, as before described; or the two sheets may be secured together by rivets, if preferred.

I claim as my inventionl. A compound fire-proof fabric composed of a sheet woven of asbestus and a pliable backing of canvas or other strong material, substantially as set forth.

2. A compound fire-proof fabric composed of a sheetwoven of asbestus and a backing of canvas or other strong material secured to the sheet of asbestus by sewing, substantially as Set forth.
